One for All: The Frauscher Wheel Sensor RSR110

Inductive wheel sensors are reliable, robust and flexible. These characteristics make them the ideal basis for existing and new applications in the railway industry. Martin Rosenberger, Chief Technology Officer (CTO) at Frauscher, presents a few examples.

Inductive wheel sensors are now being used in many railway markets around the world as a basis for axle counters. Their key function is track vacancy detection. In this function, they are also often used as signal generators for level crossings.

The establishment of the technology in different regions and railway segments around the globe does however mean that new areas of use are constantly being discovered for wheel sensors. Their possibilities are wide-ranging. In different installations, they can therefore reliably provide information about the presence of a train, its speed or direction of travel. Wheel centre pulses or wheel diameters can also be evaluated.

Flexibility of course plays a significant role here. And in order to meet the project- or market-specific requirements, models already established elsewhere have to be adapted in some circumstances. This always occurs as a balance between the conflicting priorities of demand, technical characteristics and know-how.

It was from here that the key points for the development of the Frauscher Wheel Sensor RSR110 were derived, which, due to its open, analogue interface, can be easily and quickly integrated into any infrastructure. Nowadays, this sensor is available in two system variants: the RSR110d contains two sensor systems, the RSR110s has one sensor system. Very individual systems can therefore be set up with the RSR110 which are supplied by the wheel sensor with precise measurement data.

Strong Partner for Innovative Systems

Increasing electrification of railway lines means that installations for different tasks in the railway industry have to satisfy ever-increasing challenges in fields such as EMC. Manufacturers of such systems often rely on inductive wheel sensors these days which, also demonstrate a level of robustness with respect to electromagnetic compatibility.
